Enabling FCIP

Detailed Steps

Note     In Cisco MDS SAN-OS Release 2.0 and later and NX-OS Release 4.x, there is an additional login prompt to log into a switch that is not a part of your existing fabric.

To create and manage FCIP links with DCNM-SAN, use the FCIP Wizard. Make sure that the IP Services Module is inserted in the required Cisco MDS 9000 Family switch, and that the Gigabit Ethernet interfaces on these switches are connected, and then verify the connectivity. The procedures for creating FCIP links using the FCIP Wizard are as follows:

To create FCIP links using the FCIP Wizard, follow these steps:

  1. Click the FCIP Wizard icon in the DCNM-SAN toolbar .
  2. Choose the switches that act as endpoints for the FCIP link and click Next.
  3. Choose the Gigabit Ethernet ports on each switch that will form the FCIP link.
  4. If both Gigabit Ethernet ports are part of MPS-14/2 modules, check the Enforce IPSEC Security check box and set the IKE Auth Key. See the Security Configuration Guide, Cisco DCNM for SAN for information on IPsec and IKE.

    5. Check the Use Large MTU Size (Jumbo Frames) option to use jumbo size frames of 2300. Since Fibre Channel frames are 2112, we recommended that you use this option. If you uncheck the box, the FCIP Wizard does not set the MTU size, and the default value of 1500 is set.

    Note     In Cisco MDS 9000 SAN-OS, Release 3.0(3), by default the Use Large MTU Size (Jumbo Frames) option is not selected.

  5. Click Next.

    6. You see the IP Address/Route input screen.

  6. Select Add IP Route if you want to add an IP route, otherwise retain the defaults.
  7. Click Next.

    8. You see the TCP connection characteristics.

  8. Set the minimum and maximum bandwidth settings and round-trip time for the TCP connections on this FCIP link.

    9. You can measure the round-trip time between the Gigabit Ethernet endpoints by clicking the Measure button.

  9. Check the Write Acceleration check box to enable FCIP write acceleration on this FCIP link.

    10. See the "FCIP Write Acceleration" topic.

  10. Check the Enable Optimum Compression check box to enable IP compression on this FCIP link.

    11. See the "FCIP Compression" topic.

  11. Check the Enable XRC Emulator check box to enable XRC emulator on this FCIP link.

    12. For more information on XRC Emulator, see the Fabric Configuration Guide, Cisco DCNM for SAN.

  12. Click Next.
  13. Set the Port VSAN and click the Trunk Mode radio button for this FCIP link.

  14. Click Finish to create this FCIP link.
